Light modulation of the activity of carbon metabolism enzymes in the crassulacean Acid metabolism plant kalanchoë.
When intact Kalanchoë plants are illuminated NADP-linked malic dehydrogenase and three enzymes of the reductive pentose phosphate pathway, ribulose-5-phosphate kinase, NADP-linked glyceraldehyde-3-phosphate dehydrogenase, and sedoheptulose-1,7-diphosphate phosphatase, are activated. In crude extracts these enzymes are activated by dithiothreitol treatment. Light or dithiothreitol treatment does...
متن کاملMalate Metabolism in Leaf Mitochondria from the Crassulacean Acid Metabolism Plant Kalanchoë blossfeldiana Poelln.
The mechanisms and the controlling factors of malate oxidation by mitochondria from leaves of Kalanchoë blossfeldiana Poelln. plants performing Crassulacean acid metabolism were investigated using Percollpurified mitochondria. The effects of pH and of various cofactors (ATP, NAD(+), coenzyme A) on malate dehydrogenase (EC 1.1.1.37) and malic enzyme (EC 1.1.1.39) solubilized from these mitochond...
متن کاملModulation of Rubisco Activity during the Diurnal Phases of the Crassulacean Acid Metabolism Plant Kalanchoë daigremontiana.
The regulation of Rubisco activity was investigated under high, constant photosynthetic photon flux density during the diurnal phases of Crassulacean acid metabolism in Kalanchoë daigremontiana Hamet et Perr. During phase I, a significant period of nocturnal, C(4)-mediated CO(2) fixation was observed, with the generated malic acid being decarboxylated the following day (phase III). Two periods ...
متن کاملMalate Decarboxylation by Kalanchoë daigremontiana Mitochondria and Its Role in Crassulacean Acid Metabolism.
Mitochondria isolated from Kalanchoë daigremontiana, a Crassulacean acid metabolism plant, decarboxylate added malate to pyruvate at rates of up to 100 micromoles per hour per milligram original chlorophyll in the presence of ADP. Omitting ADP reduces this rate by approximately 50%. Antimycin A inhibits malate decarboxylation and this inhibition could be relieved by addition of aspartate and al...
متن کاملDiurnal Changes in Metabolite Levels and Crassulacean Acid Metabolism in Kalanchoë daigremontiana Leaves.
Diurnal changes in levels of selected metabolites associated with glycolysis, the C(3) cycle, C(4)-organic acids, and storage carbohydrates were analyzed in active Kalanchoë daigremontiana Crassulacean acid metabolism leaves. Three metabolic transition periods occurred each day. During the first two hours of light, nearly all of the metabolite pools underwent transient changes. Beginning at day...
